There are any number around the world. I'm trying to think of those amongst some of our closest allies, which may be of greatest interest to you.
In some instances, it may be a minister specifically and solely or entirely designated as responsible for human rights. In other instances, it may be just be a case of specifically identifying that the minister of justice, or whoever, also bears responsibility for human rights. I'm quite sure there is a portfolio within the U.K. government that has a human rights responsibility, and also within the French government.
Certainly within the global south, it is prevalent. I'm often on Amnesty's front-line human rights research missions throughout Africa and Latin America. We always end those missions with government talks, and I would be hard-pressed to think of a government who doesn't have a ministre des droits humains or a ministro de drechos humanos whom we meet at the end. It's quite a common practice.
